Left only Python, of the features:

* First, I translated all the code into syntax Python 3.5.2 (since it is found in most Linux distributions)

* I made a separate file for storing authorization data, so as not to duplicate the domain name and api key in each script

Since I am not a developer, I will be glad to hear comments and corrections

Instead of using the provided samples provided by Freshdesk, here's a sample for inserting a ticket with attachments (from azure blob storage) which uses HttpClient and default HttpContent-derived objects in stead of implementing all that finicky stream handling yourself:

// constructor:

_httpClient = new HttpClient
{
    BaseAddress = new Uri(_config.BaseAddress) // http://domain.freshdesk.com/
};

_httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", $"{_config.ApiKey}:dummypassword".ToBase64());

// add ticket method:

var requestContent = new MultipartFormDataContent
{
    // for StringContent the name *must* have quotes also, otherwise the API will complain about invalid names
    { new StringContent(ticket.EmailAddress, Encoding.UTF8), "\"email\"" },
    { new StringContent(ticket.UniqueId, Encoding.UTF8), "\"unique_external_id\"" },
    { new StringContent(_config.DefaultSubject, Encoding.UTF8), "\"subject\"" },
    { new StringContent(ticket.Description, Encoding.UTF8), "\"description\"" },
    { new StringContent(_config.DefaultStatus.ToString(), Encoding.UTF8), "\"status\"" },
    { new StringContent(_config.DefaultSource.ToString(), Encoding.UTF8), "\"source\"" },
    { new StringContent(_config.DefaultPriority.ToString(), Encoding.UTF8), "\"priority\"" },
    { new StringContent(_config.DefaultGroupId.ToString(), Encoding.UTF8), "\"group_id\"" },
    { new StringContent(_config.DefaultType, Encoding.UTF8), "\"type\"" }
};

var container = _storageContext.StorageContainer; // Azure Blob Storage container reference

// ticket.Images are a list of strings which point to each image in azure blob storage
foreach (var image in ticket.Images)
{
    var blob = container.GetBlockBlobReference(image);

    var content = new StreamContent(await blob.OpenReadAsync());
    content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");

    requestContent.Add(content, "attachments[]", $"{image}.jpg");
}

var message = new HttpRequestMessage(HttpMethod.Post, "api/v2/tickets")
{
    Content = requestContent
};

var response = await _httpClient.SendAsync(message);

var result = await response.Content.ReadAsStringAsync();

response.EnsureSuccessStatusCode();

Biggest issue I encountered is that Freshdesk requires extra quotes in the name of each StringContent. If you do not include those, the API will complain that invalid fields (e.g "email\r\n") are included in the request body, since it adds the CRLF to name of the field if it isn't wrapped in quotes...
